About ubuntu

According to “Wikipedia” : “Ubuntu is an operating system based on the Linux kernel and the Linux distribution Debian, with Unity as its default desktop environment. It is distributed as free and open source software. It is named after the Southern African philosophy of ubuntu, which often is translated as “humanity towards others” or “the belief in a universal bond of sharing that connects all humanity”.
According to 2012 online surveys, Ubuntu is the most popular Linux distribution on desktop and laptop personal computers, and most Ubuntu coverage focuses on its use in that market. However, it is also popular on servers and for cloud computing.
Development of Ubuntu is led by Canonical Ltd., a company based in the Isle of Man and owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue through the sale of technical support and services related to Ubuntu. According to Canonical, the Ubuntu project is committed to the principles of open source development; people are encouraged to use free software, study how it works, improve upon it, and distribute it”.
